Question

Ortencia made the following grades on her tests: test #1, 90; test #2, 80; test #3, 95; test #4, 90; test #5, 85. She wants to plot her progress on a coordinate plane where the test number is on the x-axis and the test grade is on the y-axis.

What is the range?

Answer 2

First, right them out, least to greatest. What order are they in?

Answer 3

Then, subtract the lowest number from the highest number. What you get is your range.
